What do you mean with the 'proprietary link'' ? Isn't that the CAN-bus between the slaves (that's the interface I used)? Unfortunately this isn't CAN. There's only one IC on the board, and it doesn't support CAN. Here's the datasheet if you're interested: https://www.ti.com/lit/ds/slusc51c/slusc51c...

This is my best first attempt. Some things may need tweaking to match your setup. I'd be interested to know if it does anything. Note that it has no way to wake the module up if it's asleep. Sending data may be enough, I'm not sure. #include "CRC16.h" #include "CRC.h" #define FRM...

Hi catphish. I connected directly to the onboard chip of the BMS modules by using 4 wires of an RS232 adaptor cable then using the TI software. Tried to use the software thankfully offered by FJ3422 but couldn’t extract what I thought was the simple cell voltage reading part. Any assistance to be a...

I have managed to comms to the BMS but only using the Texas Instruments software What hardware are you using to talk to the battery module? Since my last reply I've spent a few hours reading the datasheets and trying to get the BMS Slave (the thing attached to the battery) to respond but haven't ha...

I'm embarking on a moderately similar project, and wanted to say hi. I'm hoping to convert a VX220 using a Tesla SDU, openinverter, and some of my own software to glue everything together. While I haven't decided on batteries yet, I have some of the same battery modules as you, and I'm currently att...
